:pkill hammer
:hammer synctid /Backup1/Data quick
:hammer mirror-copy /Backup1/Data /Backup2/Data
:
:at the end of /etc/rc.shutdown
:
:the "pkill hammer" command kills all "mirror-stream" processes but
:does not kill any kernel helper threads. Is that OK?
:
:also while starting "hammer mirror-stream" using /etc/rc.local there
:are 3 mirror-stream processes.

:Is this OK? I have a doubt since you said " The mirroring utility is

    It may not die immediately when you kill it.  You definitely
    want to use the lockf(1) utility to ensure that you are only
    running one thing at a time (as appropriate for what you are
    doing).

    hammer mirror-stream forks itself twice so it can exec ssh.  It
    should exec ssh via those forks though I'm not sure what actually
    shows up in the ps.
